This latest bomb threat made to a Jewish communal target comes over 2 months after Israel’s anti-fraud squad arrested 19-year-old Israeli-American Michael Kaydar on March 23, who is accused of making hundreds of threats to Jewish organizations in Europe, Australia and New Zealand over a period as long as three years.

Mere hours later, the Jewish Community Center (JCC) in Dallas, Texas, was evacuated after receiving a threatening phone call. On April 1, Temple Beth Torah Sha’aray Tzedek in Pompano Beach, Florida was also targeted.

Kaydar remains uncooperative with the ongoing investigation, refusing to let officers search his computer and attempting to grab the firearm of the officer placing him under arrest. The Israeli army previously refused to draft the teen, who has lived in Israel for many years, after finding him unfit for service due to a brain tumor. The investigation is being conducted alongside the FBI, and the United States will likely request Kaydar’s extradition.

Nearly half of the country’s Jewish community centers have received bomb threats in 2017.

North American JCC leadership was briefed by, and consulted with, the FBI on the morning of March 23. “We are gratified by the progress in this investigation, and applaud the commitment and leadership of the FBI and other federal agencies, Israeli law enforcement, and local law enforcement across the United States and Canada,” said JCC Association of North America’s president and CEO, Doron Krakow.

Seventy-three of the 151 JCC locations in the United States have received bomb threats — over 48%. Five Anti-Defamation League locations, several Jewish day schools, two synagogues and a Jewish children’s museum in Brooklyn’s Crown Heights area have also received threats. Several public schools across the country have also been inundated with anti-Semitic graffiti, swastika leaflets and “offensive posts.”

On March 7, New York City Mayor Bill de Blasio noted: “We have not seen anything like this in many years, this level of hatred directed against the Jewish community, this many threats. So we are really in an unprecedented moment.”

That same day, ADL’s CEO, Jonathan Greenblatt, issued a statement calling on the Trump administration and Congress “to take concrete steps to catch those threatening the Jewish Community.”

“Four ADL offices in Atlanta, Boston, New York, and Washington, D.C., received telephoned bomb threats today. This is not ‘normal,’” Greenblatt added.

On February 28, the JCC Association called for federal action. On March 1, the organization spoke with representatives from the Department of Homeland Security. Later in the day, Homeland Security Secretary John Kelly released a statement calling the threats and harassment “unacceptable and escalating,” and noted that he directed his department to “heighten outreach and support to enhance public safety.”

David Posner, who as director of strategic performance at the JCC Association advises local JCCs on security policies and practices, released the following statement in response:

“The Department of Homeland Security is offering concrete help at a time when our JCCs need to hear that the federal government is prioritizing our security. DHS has promised that its protective security advisers, stationed in all 50 states, will be in contact with JCCs within the next week, offering their expertise on protective measures, threat reporting and security awareness. We look forward to working with DHS through this unparalleled level of assistance, which comes as very welcome at an extraordinarily stressful time for JCCs and the diverse communities they serve. We again thank Secretary Kelly and DHS.

“We urge fellow federal agencies to follow DHS’s lead and apply all resources necessary toward finding the perpetrator or perpetrators of these disruptive, harassing calls, and bringing them to justice. We are relieved no one has been harmed, but the atmosphere created by these calls hangs over our communities and will only be lifted once someone is caught and punished.”
